For large osteochondral defects (> 9.6 cm2) of weightbearing areas of the knee, techniques established for smaller sized lesions such as drilling, microfracturing, and transplantation of osteochondral plugs (OATS, Mega-OATS) provide only insufficient clinical outcomes (12, 13). Treatment of osteochondral injuries and osteochondritis dissecans (OCD) is quite controversial and has received recent attention in the literature. Although wearing a brace or cast may ease the discomfort of an osteochondral lesion, they are usually not enough to remedy the problem permanently, except in children, who can respond well to non-surgical treatment. https://doi.org/10.1016/S0278-5919(05)70309-4. The advantage of this treatment is that the patient's own cartilage is used to repair the damaged area. Significant articular cartilage incongruity often causes mechanical joint dysfunction and eventual cartilage deterioration, resulting in osteoarthritis. einstein. Ideally, defects of the articular cartilage in the knee would be replaced with normal hyaline cartilage. Knee microfracture surgery is a common surgical procedure used to treat the surfaces of the knee joint when they have become damaged.

Together with the newer techniques OATS and ACI, BMS was identified as an effective treatment strategy for OCD of the talus. Isolated lesions of cartilage or subchondral bone are not considered an OCD 6.. Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm 2), often with associated bone loss. Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. Significant articular cartilage incongruity often causes mechanical joint dysfunction and eventual cartilage deterioration, resulting in osteoarthritis. Osteochondral defects generally linger or get worse unless they’re treated.

Physiotherapy plays a crucial role in rehabilitation and recovery following knee microfracture surgery. For adults, such a condition usually requires surgery. Trauma, osteochondritis dissecans, osteonecrosis, osteochondroses, and hereditary epiphyseal abnormalities can cause osteochondral lesions in the knee joint.25, 61, 62, 72 When an osteochondral defect persists in a weightbearing portion of the knee joint, degenerative arthritis of that compartment can result. For instance, if the anterior cruciate ligament were to rupture, the tibia can slide forward (subluxate) and impact the femoral condyle (a so-called kissing contusion). * A. Autologous chondrocyte transplantation (ACT or ACI) to treat cartilaginous defects of the knee is considered medically necessary when all of the following criteria are met: 1. Osteochondral defect is a broad term that describes the morphological change of a localised gap in the articular cartilage and subchondral bone 5.It is often used synonymously with osteochondral injury/defect and in the paediatric population.

Unless the injury is extensive, it may take months, a year or even longer for symptoms to develop. Cartilage can be focally damaged, producing a “pot hole” in the joint surface, when the knee ligaments are injured. The fixed sutures on the femoral surface did not have much effect on the joints, and the patients did not feel any discomfort. A one-step treatment for chondral and osteochondral knee defects: clinical results of a biomimetic scaffold implantation at 2 years of follow-up. Should the cartilage be disrupted, then microdrilling or micropicking of … A review of a Polish registry found that more than half of patients undergoing knee arthroscopy had chondral defects, with 5.2% having Outerbridge Grade III or IV lesions.

Published by Elsevier Inc. All rights reserved. The treatment of chondral defects of the knee can depend upon the location and size of the defect. Patient- and lesion-specific factors must be identified when evaluating a patient with an articular cartilage defect. Published by Knee Surgery, Sports Traumatology, Arthroscopy : Official Journal Of The Esska, 27 June 2017 . For small-sized defects with intact cartilage, our treatment of choice is Retrograde Drilling of the lesion and filling it with a special bone cement. A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones). Large, focal articular cartilage defects of the knee (> 4 cm) can be a source of significant morbidity and often require surgical intervention. Address reprint requests to E.

The use of minced articular cartilage for the repair of osteochondral articular cartilage defects of the knee is considered experimental and investigational. In general, those that are on the end of the thigh bone, the femur, are the ones that are easiest to treat and have the best outcomes. Pathology ranges from the young child with open physes and an OCD lesion, to the middle-aged athlete with an osteochondral fracture secondary to trauma. Treatment options to restore joint congruity vary widely from nonoperative closed treatment to arthroscopic drilling, with or without fixation, to tissue transplantation or reconstructive procedures.
